If you are not using Rails, set Capybara.app to your rack app:

As you want to run tests against external application, you should set Capybara.app_host instead of Capybara.app.

I haven't used capybara-mechanize but I think it may be not the best driver to use to test external non-Rack application. Mechanize inherits from Racktest and Racktest is for testing apps with Rack interface (mostly Rails). If your app doesn't have Rack interface, then capybara-mechanize may be not the best choice.

I recommend you to use the built-in selenium, poltergeist, capybara-webkit or terminus

Also your code can be written a bit nicer using Capybara.configure:

Capybara.configure do |config|
  config.run_server = false
  config.default_driver = :selenium
  config.app_host = 'https://www.google.com' # change url
end
